SECFCATION forming pari; 'of Let-ters atent No. 650;?40, dated. viay 29, 1900.

Application led Octber 21, 1898.

To @ZZ wwm, t may cmwerlt:

Be it known that I, CHARLES A. WRIGHT, a citizen of the United States, residing at Brock# ton, in the county of Plymouth and State of Massacl1usetts,have invented certain new and useful Improvements in Vehicle-VVheels, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinven tion relates to vehicle-wheels 5 and its object is to provide a wheel-hub so constructed as to facilitate the tensioning of the spokes.

The novel features of the device will be fully described hereinafter and defined in the appended claims.

In the accompanying drawings, Figure lis a perspective view of a wheel embodying the invention, and Fig. 2 is an enlarged longitu dinal central section of the hub.

The reference numeral 1 designates the wheel felly and tire, and 2 the spokes.

The hub consists of asleeve 3, formed with a central integral collar 4t and adjustable ends 5. The sleeve 3 is preferably formed with an internal annular oil-groove G, and its ends 7 and 8 are externally screw-threaded with threads of opposite pitch, and the end sections 5 of the hub are correspondingly threaded to engage the threads of the sleeve. Surrounding the collar t of theY sleeve is a ring 9, preferably made integral with the collar and having its ends 9a projecting laterally beyond the sides of the collar, leaving spaces l0 between the ring and sleeve. These spaces are closed by annular flanges l1, projecting inwardly from the ends 5. The periphery of the ring 9 is preferably of polygonal form to facilitate the application of a wrench thereto. The flanges l1 are oppositely externally threaded for engagement with corresponding internal threads on the interior of the projecting ends 9a of the ring. The purpose of this construction is to effect the application of the actuator (comprehended by the sleeve 3 and ring 9) to the end sections at a plurality of points-that is to say, the adjustment of the spoke-retaining sections would be attended with more or less binding of the engaging threads of the sleeve ends 7 and S as the move- Serial No, 694,208. (lit model.)

scribed is otherwise essential, as it is desir' able to have the wrench-engaging surface practically in the circumferential plane of the end or hub sections, and in order to protect the engaging surfaces of the spoke-sec'- tions and sleeve 3 from dust and dirt and at the same time allow for relative movement of the parts the anges 11, telescoping with the projecting ring ends, must be provided.

The ends of the spokes are secured to the ends 5 of the hub, as shown, and their outer ends'to the felly 1.

The collar 4 enlarges the circumference of the sleeve at the central portion of the latter, thus affording an enlarged grasping-surface for the wrench in turning the sleeve and correspondingly increasing the leverage in turning said sleeve, and the lateral end extensions of said ring 9 increase the width of the grasping-surface.

The closing of the annular spaces 10 by the flanges 11 of the ends 5 prevents the accumulation of dirt below the ends 9a of the ring 9.

By turning the hub-sleeve the hub ends are moved in or out, owing to the right and left threaded engagement between these parts.

' I claim@ 1. In a wheel -the combination with a felly and spokes of a hub comprising a sleeve having oppositely externally threaded ends an intermediate annular collar surrounded by a ring projecting beyond the sides thereof, and a pair of spoke-retaining sections oppositely internally threaded for engagement with the nular collar and a ring having an angular exterior face, oppositely interiorly threaded spoke-retaining sections on the sleeve and provided with oppositely-extending annular flanges interitting with the rin g, the contiguous faces of ring and flanges being correspondin gl y threaded.

In testimony whereof I aix my signature 1n presence of two witnesses.

CHARLES A. VRIGHT.
